Application filed August 9, 1897. Serial No. 647,560. (No model.)

To a/ZZ whom, it may concern,.-

Be it known that I, WILLIAM BORRMAN, a citizen of theUnited States,residing at Norfolk, in the county of St. Lawrence, in the State of NewYork, have invented a certain new and useful Improvement in Balance-Pumps, of which the following is a specification.

My invention relates to pumps adapted for lifting water from a well orpool and for discharging the same at some suitable elevated point.

Prominent objects of my invention are to reduce to a minimum the powerrequired in operating the pump, to increase the pumping capacity, toreduce the strain and wear and tear upon the operating mechanism, and toaccomplish such results in asimple, economical, and efficient manner.

In a pump characterized by my invention two columns of water areintermittently lifted and discharged by means of a couple of sets ofcoacting pumping membersthat is to say, a couple of sets of pumpingmembers whereof those in each set cooperate with one another to lift oneof the columns of water when the pump is in operation. In these two setsthe members which simultaneously support the two columns of water duringthe operation of the pump are interconnected, so as to place the weightsof such columns continually in opposition to one another-that is to say,so that the downward pull on the part of either column will be alwaysopposed by the downward pull on the part of the other. In this way thetwo columns of water will tend to balance or support one another, and sowhen either one is elevated the weight actually lifted will not be theentire weight of such column, but will be the weight of the same lessthe extent of opposition on the part of the other column.

The accompanying drawing is a View, partly in elevation and partly insection, of a pump embodying my invention.

In this arrangement a couple of verticallydisposed pumping-barrels A andA are arranged in position above the well or pool from which the'wateris to be drawn, with their lower ends immersed therein. These barrels Aand A' are of substantially the same length,

(a portion of which is omitted from the drawing for convenience ofillustratiom) which length is such as to allow the elevation of thewater to the predetermined elevated point. Said barrels are respectivelyprovided near their upper ends with suitable discharge nozzles or spoutsa, and d and at points below the latter with suitable upwardly-openingpumping-valves d2 and as.

A couple of pumping-plungers B and B are arranged, respectively, withinthe barrels A and A and above their pumping-valves d2 and d3 and arerespectively constructed with upwardly-opening pumping-valves b and b',which latter are adapted to coact, respectively, with one and the otherof the barrel-4 valves a2 and d3, so as to cause a pumping action in oneor the other of the two barrels A and A when one or the other of them issuccessively shifted in alternately reverse or opposite directionsrelatively to one or the other of the barrel-valves. As a simple anddesirable way for producing this relative shifting action between thecoacting plungers and barrels the said barrels are arranged forcorresponding and simultaneous vertical re= ciprocation insimultaneously opposite directions, a simple and efficient arrangementbeing to suspend the barrels from and pivotally connect their upper endsto the opposite ends of a vertically-swinging walking-beam C, which ispivotally supported at a point midway between its ends-as, for example,by a hanger D, attached to an upper cross-beam E. In this way the twocolumns of water are successively and alternately lifted by the barrelsan extent equal to the extent of reciprocation on the part of the latterand are alternately and successively supported by the plungers duringthe periods intervening between their periods of elevation, andtherefore in either barrel simultaneously with the elevation of theother, so as to allow their upper portions to be alternately andsuccessively discharged through the barrel discharge nozzles or spoutswhen the latter are alternately and successively lowered to an extent tocome into position below their upper ends. It will thus be seen thatwhile the two barrels form, respectively, with one and ICO the other ofthe two plungers with which they coact a couple ofsimultaneouslybperating pairs of coacting pumping members such barrelsalso form, respectively, with one and the other of the two plungers withwhich they do not coact a couple of alternately-operating pairs ofsimultaneously-supporting members. The barrels A and A' could be thusreciprocated by any suitable means, a simple and convenient arrangementbeing to apply to one of them-as, for example, to the barrel A-the upperend of a reciprocating pitman F, which is operated by a crank Gon arotary shaft H. The bearings for the shaft H are conveniently mounted ona lower crossbeam J, which is extended horizontally above the well orpool and is desirably provided with suitable guides for the barrels Aand A', as indicated by dotted lilies in the drawing.

The non-coacting plunger and barrel comprising each pair of the twoalternately-operating pairs of simultaneously-supporting members areconnected together in opposition-that is to say, they are so connectedas to place the weights ofl the two columns of water which theysimultaneously sustain in opposition to one another, so that the onewill tend to balance the other. Thisis clearly shown in the drawing,where, it will be observed, the column of water at the right ispractically supported or upheld by the plunger B', while the column atthe left is practically supported or upheld by the barrel A by reason ofits closed valve 0.2, and as the said barrel A and plunger' arerespectively attached to opposite ends of the lever M' the two columnsof water will thereby tend to counter-balance each other. As anexceedingly simple and effective arrangement the upper ends of theplunger-operating rods L and L' are respectively connected to the endsof acouple of horizontallyarranged levers M and M', which latter havetheir opposite ends in turn respectively connected to one and the otherof the two barrels A and A' and are fulcrumed at points intermediate oftheir ends-as, for example, by being supported by a couple of hangers Pand P', respectively, which are attached to the upper cross-beam E. Inthis way the two columns of water are, in effect, simultaneouslysuspended from the opposite ends of one or the other of a couple oflevers in altei-nation, and their weights therefore tend to continuallycounterbalance one another.

The levers M and lll' are of course vibrated or swung about theirfulcrums by the reciprocation of the barrels A' and A, to which they arerespectively connected, and so operate to reciprocate the plungers B andB' synchronously with their coacting barrels. In order, therefore, tostill allow a relative shifting movement between the plunger and barrelcomprising, respectively, one and the other of the two pairs of coactingpumping members, the levers M and M' are respectively fulcrumed atpoints between their longitudinal middles and their points of connectionwith the plunger-operating rods L and L', so that while the plungerswill reciprocate synchronously and in the same direction with theirrespectively coacting barrels they reciprocate to an extent less thanthe extent of reciprocation on the part of the latter'. The exactlocation of the points of fulcrum of the levers M and M' could beanywhere bctween ther longitudinal middles and their respective pointsof connection with the plunger-operating rods L and L'. It will beobserved, however, that the nearer such fulcrums are situated to thelongitudinal middles of the levers the nearer to a true counterbalancewill the opposition of the two columns of water become, but at the sametime the less will be the extent of relative shift on the part of thecoacting members comprising, respectively, one and the other of the twopumping sets and that on the other hand the nearer such fulcrums aresituated to the points of connection of the plunger-operating rods thegreater will be the extent of relative shift between such coactingpumping members, but at the same time the farther from a truecounter-balance will the opposition of the weights of the two columns ofwater become. I therefore desirably locate the fulcrums for such leversat points substantially midway between the longitudinal middles thereofand the points of connection thereof with the plunger-operating rods,and thereby cause the opposition of the weights to one another toapproach as nearly as possible to a true counterbalance without at thesame time lessening to ,too great an extent the amount of relative shiftbetween the coacting pumping members.

In order to permit the proper vibratory or swinging motion of the leversM and M', they are pivotally connected to the plunger-operating rods Land L', respectively, and also to the hangers P and P', respectively,and have sliding connections with the barrels A' and A,respectively-such, for example, as the pins N and N' on the barrels andthe slots m and m' in the levers.

The water discharged from the barrel-nozzles a and a' can beconveniently received by a suitable trough Q, supported by the lowercross-beam J by mean-s of suitable legs R R, and can be conveyed fromsuch trough for use by means of a pipe S, attached to the side thereof.
